Abstract (en)
[origin: EP3787147A1] In order to simplify a wiring of power supply system (1) including a plurality of power storage modules (M1 to M3) and management devices (10 to 50), a plurality of sub-management units (10 to 30) respectively manage the plurality of power storage modules (M1 to M3). Main management unit (50) manages the plurality of power storage modules (M1 to M3) via the plurality of sub-management units (10 to 30). Main management unit (50) and the plurality of sub-management units (10 to 30) are daisy-chain connected by power line (40v). Main management unit (50) can supply power from power storage unit (2) other than the plurality of power storage modules (M1 to M3) to the plurality of sub-management units (10 to 30) via power line (40v). Main management unit (50) and the plurality of sub-management units (10 to 30) respectively include communication units (12 to 32). Each of communication units (12 to 32) superimposes a communication signal on power line (40v).
